An extensive collection of QL emulators running on various platforms including Amiga, Atari, DOS, Linux/Unix, Mac and Windows. Where the emulator is still well supported, perhaps updated quite often, I've linked to the relevant website rather than include the package for download here, to help make sure you get the latest version. In any case, I've tried to provide web page addresses for information and general support even where I've placed the archive on this page.
QLay is a set of QDOS QL emulators for DOS, Windows and Linux by Jan Venema of The Netherlands. This is a freely distributable emulator with no restrictions. You can download the most recent versions from Jan's Web site: http://web.inter.nl.net/hcc/A.Jaw.Venema
QLATter (39K) - Al Feng's utility for QLay users. Provides a simple to use file handling front end.
QLAY2 is a development of QLay to run on Windows 2000/Windows XP systems (also seems to work on Windows 98 SE). The update is by Jimmy Montesinos. The support website for QLAY2 is at http://www.jadiam.org/QL/QLay2/
QL2K is a further development of QLay, also for Windows 2000/XP systems, by Jimmy Montesinos. The support and download site for QL2K is at http://www.jadiam.org/QL/. QL2K is registerware - it is free to download and use, but you need to register the emulator (free of charge) with the author.
QPC1 is a QL emulator using SMSQ/E running in DOS. Internet address listed under QPC2 below. QPC1 is a QL emulator using SMSQ/E running on DOS/older Windows machines. It needs a minimum of a 486 processor. Instructions document (plain text) in the zip file, or PDF file below.
Download QPC1 v1.52 - if you need a DOS version! (zip file) (196K)
News: as of 2014, QPC2 version 4 full version is now freely available to download!
QPC2 is a QL emulator, based upon the SMSQ/E variant of the QL operating system. Since version 4 appeared on the cover CD of the last issue of QL Today, QPC2 has now been made freely available to download. QPC2 runs in Windows, and features standard QL video modes plus high resolution and higher colour modes (8-bit colour like the Aurora card and 16-bit colour). Mass storage is via the QXL.WIN filing system as also used by QXL, uQLx and QemuLator, for example, and there is also support for reading and writing QL format floppy disks and reading raw images of QL disks, plus a DOS device to read and write form/to Windows hard disk. There's a TCP/IP access system for web access and email using programs like Lynx, QPOP3 etc from Jonathan Hudson. Also, a sound driver based on the QLSSS (QL Sampled Sound System). QPC2 is a very fast emulator, which uses SBASIC, which is SuperBASIC compatible (only much faster!) and can be set to use very large RAM memory. Includes a sample QPCdemo.win file containing some useful free software.
Download QPC2 - this is a Windows installer .exe program, just follow its prompts to install QPC2 v126.96.36.199. (2.8MB)
QPC2 for Mac OSX

QemuLator Lite for Apple Macintosh is written by Daniele Terdina and is Shareware. There are versions for 68K Macs and for PowerMacs. Further details from the author's Web site at: http://www.terdina.net/ql/MacQL.html
QemuLator is now available for the Mac OSX operating system. Features include: QL 68008 processor emulation, keyboard, display (512x256x4, 256x256x8), interrupts, file system (access to Mac files, QDOS floppy disks, QXL.WIN files, .ZIP and .QLPAK packages, microdrive and floppy images), sound, built-in ram disk, mouse support, partial Gold Card emulation (to allow SMSQ/E to run). System requirements: Mac with an Intel processor and OS X version 10.5 or later. If you have a PPC Mac and OS X 10.4 or earlier, you may still be able to run the old version for 68k Macs. Further details and shareware download from the author's website at http://www.terdina.net/ql/MacQL.html
QemuLator for Windows is also written by Daniele Terdina and is Shareware (registration of about 46 dollars at the time of writing). Further details from the author's Web site at:www.terdina.net/ql/q-emulator.html. This emulator can emulate a standard QL, a Gold Card QL, or even a fast QL system with up to 16MB of RAM! It can run some versions of SMSQ/E or use QDOS ROM images (including Minerva), can access QXL.WIN or native file systems and has a built in TCP/IP system, so that you can use email and web browser programs such as those from Jonathan Hudson. The latest versions of QemuLator can also emulate Aurora 256 colour with Aurora/Gold Card version of SMSQ/E and Q60 16-bit colour displays if you write direct access code, extract QL program files from .zip files downladed from the internet (no more loss of QL program file headers!) amd even self-contained QLPAK software archives. The emulation of QL speed is now more precise. Built in dot-matrix printer emulation means you can print to more types of printers. Support for QL Sampled Sound System and smoother graphics thanks to pixel interpolating.
QDOS4Amiga is a QDOS emulator for the Commodore Amiga,
by Rainer Kowallik and Mark Swift. It is freeware. Up to date copies
may be obtained from most Ami-Net sites. See the README1.TXT
QDOS Classic for Amiga is a QL emulator for the
Commodore Amiga by Mark Swift. QDOS Classic for Amiga is closely
related to QDOS Classic for Q40 by the same author. Freeware. QDOS Classic is also available below for Q40/Q60.
QL Kick ROM for UAE
- UAE is a computer emulator which emulates the hardware of the
Commodore Amiga range of computers. Released under the GNU General
Public License, UAE is free software. UAE nowadays stands for
Ubiquitous Amiga Emulator or Universal Amiga Emulator, since it is
available for Windows, Mac, Linux and other platforms. QDOS
Classic runs on Q40, Amiga and
RAW QDOS Disk Images
QDOS support disk for QDOS Classic v3.25
- A set of utilities, some for use with QDOS Classic Amiga, some with
QDOS Classic Q40. Includes for Q40: the Q40 SoftROM toolkit, current
QDOS Classic ROM for Q40, Q40 Utility ROM that shipped with early Q40s
and a simple demo of hi-res screen modes on Q40. For Amiga: Example fo
how to use the Amiga blitter in QDOS, a hack to play audio CD tracks
from an Amiga SCSI drive, an Amiga palette editor for QDOS and a patch
over TAS instructions with Amiga-friendly code. Plus some program
patches and miscellaneous QDOS programs - see the list in the Readme
text file below.
QLem is an emulator for certain Atari ST
machines, by Johan Klockars. Freeware. Details from the Ancient
File Library at
May be downloaded here as ZIP or LHA files:
QL2ST v3.0 is an associated QL disk transfer
utility for use with QLem. QL2ST has two functions - initialise disks in
the Sinclair QL format and convert files from a QL format disk to a TOS

ql2st.lzh - download QL2ST as LHA file (14K)
TOSforQL is an emulator that allows certain
programs written to run under TOS on the Atari ST to be run under QDOS.
The emulator works by intercepting calls to the TOS operating system and
mapping them onto the equivalent QDOS operating system calls.

ST_Ql_EmulatorLoad.zip - ST/QL Emulator Load Program v1.7 The QDOS_IPL software is a replacement for the normal load programs that have been provided with the Atari ST QL Emulators. The impetus for its development was the needs of hard disk users. The aim was to minimise (ideally eliminate) the need to use a floppy disk during the process of loading the QL emulator. (D.J.Walker) (13K)
SMSQmulator, the SMSQ/E machine emulator under Java was launched in January 2013. You can use this on pretty much any system that runs the Java 6 or 7 language, including Windows, Mac OSX and Linux. It is not a QL emulator, strictly speaking, it is an MC68000 emulator which allows you to run programs which work with SMSQ/E. Programs which rely on strictly QL features such as fixed address system variables or screen locations may not work. Programs which rely on later processors such as 68020, 68040, or 68060 (e.g. programs written specifically for Q40 or Q60) may also not work on it. That said, this emulator is free and the sources for it are available.
Running SMSQmulator is easy if you have Java installed on your system - just place all the files in a directory on your hard disk and run (e.g. double click in Windows) the "SMSQmulator.jar" file. It comes with a good PDF file manual and supports floppy disk image reading, QXL.WIN, Native File Access (NFA) drives, and SMSQ File Access (SFA). Sound output is supported both via the usual BEEP command plus the Sampled Sound System (QLSSS) within limitations of the Java sound drivers.

QDOS Classic for Q40/Q60 may be downloaded from my Q40 page, or from the official Q40 website at www.q40.de. QDOS classic, as the name implies, is an implementation of the traditional QL QDOS operating system rather than the SMSQ/E operating system. There's also a version of Linux for Q40 and Q60 - click on the link above to Claus Graf's Q40 website for further details.
